I fired up my Xbox 360 today and installed the new "Experience". It is a free download from Xbox Live and replaces the original "Blade" front end with a completely different look which I reckon is much easier to navigate. It also lets you create mini-avatars of yourself to use for your interaction with games and other Xbox 360 users. I've no idea where they got the idea for this. I spent a few minutes tweaking my avatar appearance to add my distinctive good looks, which was great fun. Or not.
One of the wonderful things about modern software based devices is the way that they can sprout new behaviours years after you got them thanks to the magic of the firmware upgrade. I now have what feels like a brand new replacement of my console. If you have an Xbox 360 you really must check this out.
